Why won’t Java install on my hosted Mac?

Java looks for an actual display plugged into the Mac mini in order for it to install without error. However, none of the Mac servers in a data center environment like at MacStadium have physical displays connected.

As a solution, we have verified that installing a GPU enabler dongle — which we include as a free add-on to all Mac subscriptions — will convince macOS a display plugged in. This allows Java to install without error. Other benefits of the GPU enabler dongle including performance improvements and increased resolutions are noted in our blog.
